OF INDIANAPOLIS, INDIANA, A CORPO- INLET FOR PNEUM'ATlC-DESPATCH TUBES.

SPECIFICATION forming part of Letters Patent No. 705,884, dated July :29, 1902.

Application led October 14, 1901. Serial No. 78,558. (No model.) i

To aM whom t may concern:

Be it known that I, FRED R. TAIsEY, of Indianapolis, county of Marion, and State of Indiana, have invented a certain new and usefulInletforPneumatic-DespatchTubes; and

I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which like numeralsrefer to like parts.

The object of this invention is to provide means for introducing ,a carrier into a pneumatic-despatch tube Without vany admissionv of air through the inlet.' The admission of air when a carrier is inserted into a pneu- 15 matic-despatch tube weakens the force of the air-current in the tube and temporarily stood from vthe accompanying drawings andY z 5 the following description and-claims.

In the drawings, Figure lis an elevation of the inlet for a pneumatic-despatch tubegand' a portion ofthe tube, parts being broken away and in section and a carrierbeing in po- 3o sition for introduction into the tube. Fig..2, is a central'verticalsection-of what is shown in Fig. 1 with thecarrier omitted. Fig. 3 is a section on the line 3 3 ofFig.12, the crank being shown in dotted lines and broken.

In the drawings, represents a support for the mounting of the device.

11 is a pneumatic-despatch tube.

I provide an inlet-chamber in the inlet-tube 12 and the valve-chamber 13. Said valve- 4o chamber 13 contains the lower valve 14.

15 is a carrier. The inlet-chamber isrclosed at its upper end by a valve or'lid 16, pivoted at one side at 17 to the inlet-tube12 and heldclosed by the spring 18, coiled about the pivot-pin 17.

19 is a finger-piece for opening the upper valve or lid.

The lower valve 14 is a horizontally-.oscillating plate with a shank secured to the shaft Y 20, the lower end of which shaft has a bear- 5o ing at 21 in the bottom of-the valve-chamber 13, and the upper end has a bearing in the base 22 of the inlet-tube12. Saidvalve has a leather washer 23 secured on its under side, and it isheld normally over and'closing the 5 5' passage-way from the valve-chamber 13 into the pneumatic tube 11 by means ofthe spring 24, coiled about the shaft 2O.l f Said valve is 'moved from its normal 'position'by .the crank 25. v `T he valve 14'has an upwardly-extending collar 26 to support the end of the carrier, as shown in Fig. 1. Itis provided with a slot or n otch 27 on one side to permit the lateral movement of the valve when a carrier having a pin 28 is resting on the collar 26,' as appears in Fig. v1. The valve-chamber 13 has a downwardly-extending sleeve`29, in which the upper end of the despatch-tube 11 issecured. In the bottom of the valve-chamber 13 a rib 7o or upward extension 30 is provided as a track to support the valve14 and washer 23 during the lateral movement ofthe same vfrom the position shown in full-lines in Fig. 3 to the position shown in dottedlines.

The operation is as follows: The lid or valve 16 is elevated into an open position and the carrier 15 dropped into the inlet-chamber and the lid or valve 16 released. The lid or valve will then close the upper end ofthe inlet- 8o chamber and the carrier/15 will rest endwise on the collar 26 of the'valve 14, asshown in Fig. l. Then the crank f25is moved in the direction of the arrow in Fig. 3, causing the valve 14 to be moved from over the entrance 85 to the despatch-tube 11, whereupon the carrier 15 will drop into and enter said tube. The crank 25 is then released, and the spring 24 throws the valve14back to close the entrance to said despatch-tube 11. 9o

From this explanation it is obviousthat while the carrier 151is being inserted into the inlet-chamber, and after the upper end of the inlet-tube is closed and the lower valve is opened to permit the carrier to enter the despatch-tube no appreciable amount of air will pass from .the inlet-tube into the despatchtube. Hence the carrier can be introduced into the despatch-tube Without aecting the force of the current therein or the movement of any other carriers that may be in the tube.

What I claim as my invention, and desire to secure by Letters Patent, is-

l. An inlet for a pneumatic-despatch tube consisting of an inletchamber,a spring-closed lid or valve at the outer end thereof, a springclosed valve for closing the outlet from said chamber, and means for moving said lastnamed valve laterally out of a closing position.

2. An inlet for a pneumatic-despatch tube consisting of an inlet-tube adapted to serve as a guide for a carrier, a valve-chamber s ecured to the inner end of said tube which is extended at a right angle from said tube, a valve for closing the outlet from said valvechamber that is pivotally mounted,and means outside the valve-chamber for oscillating'said valve.

3. An inlet for a pneumatic-despatch tube consisting of an inlet-tube, a valve-chamber secured to the inner end of said tube which is extended at a right angle from said tube, a valve for closing the outlet from said valvechamber that is pivotally mounted, means outside the valve-chamber for oscillating the valvetlierein, and a rib ortrack in said casing upon which said valve moves in its oscillation.

4. An inlet for a pneumatic-despatch tube consisting of an inlet-chamber, a valve for closing the outer end thereof, a valve for closing the inneror outlet end thereof, means on the latter valve adapted to support the carrier out of Contact With the valve after the carrier has been inserted into said chamber, and external means for moving said valve out of the path of the carrier.

5. An inlet for a pneumatic-despatch tube including an inlet-chamber with an outlet therefrom to the despatch-tube, a valve for closing said outlet, means for moving said valve laterally to open said outlet, and a collar on said valve to Support a carrier before the valve is actuated, said collar being slotted on one side substantially as shown.

In Witness whereof I have hereunto aiiixed my signature in the presence of the Witnesses herein named.

FRED R. TAISEY.
